Greetings!
A new software stack usable with LimeSDR devices is available for DMR Tier 3 trunking as well as other amateur radio digital and analog FM modes.
The stack was developed and tested primarily with a LimeNET-micro v1, but it is also compatible with legacy LimeSDR, LimeSDR-mini and the LimePSB-RPCM via SoapySDR bindings.
The software is described in more detail here: New DMR Tier III trunked radio software stack for amateur radio SDR repeaters and hotspots
